To a whom it may concern:

Be'it known that I, CHARLES CORNWELL HovEY, a citizen'of the UnitedStates, residing at Bainbridge, in the county of Ohenango 5 and State ofNew York, have invented an Im-- 1 provement in Apparatus for SealingCans, ,Jars, and other Packa es by Atmospheric Pressure, of which theollowing is a specification.

have shown and described a machine for receiving the cans, jars, &c.,and in which the vacuum is established for sealing the covers and whichmachine is similar to the one shown and described herein.

In carrying out my resent invention Iemploy a machine includ mg thecans, jars, &c.', and in which the covers are'sealed by atmosphericpressure, a vacuum-tank, anair-pump, a pipe fromfsaid' machine to theair-pump and in which is located a three-way valve, a pipe from thevacuumtank to the aforesaid plpe and joined there with between-thethree-way valve and the air-pump, and a two-wayvalve in the said 1 e.lhe details of the unitary apparatus and the operation ofthe same arehereinafter described. 3

In the drawing I have represented the uni- ..tary deviceof myimprovement by an elevationin which the cover of the rece tacle is shownas open, so'as to disclose the parts therein. c n

The ,machine, illustrated for receiving the cans, jars, &., and in whichthe vacuum is established for sealing the covers and which is sim trt'othe oneshown and described in myapplication hereinbefore noted,comprises a standard a, shownas hollow, a recep tacle b, comprisin atop,.bottom,,sidesand back, and a cover shown in a horizontal p0 sition,but adapted to set up into a vertical position to close the receptacle.The platform 0 shown within the receptacle ,isad'apted-to receive thecans, 'ars, &c. the covers of which are to beseale by atmosphericpressure: cover isconnected to a rod cflwhi'ch.

' My invention relates to a unitary apparaby me March 6, 1905, SerialNo. 248,390, I

mg a receptacle receiv-' passes down through the bottom of the recep- Itacle and through the standard and is conneoted to one end of afoot-lever c, by which the said platform and the articles thereon areadapted to be raised. (Z re resents a laten also in said receptacle anconnecte to a screw-rod d, which passes up through a stuffing-boX in thecover of the receptacle and through a brace-bar d terminating in ahand-; wheel by which the screw is rotated andthe platen d raised andlowered.

6 represents a gage connected upon theto p of the receptacle with theinside, so as to indicate the vacuum piesent.

f is a vacuum tank or cylinder suitably sup ported, and 9 an air-pump,which latter may e of any well-known or desired construction. h is apipe connected to the top of the receptacle b and internallycommunicating with the receptacle and extending to the air-pump In theline of this pipe it there is a three-way valve 11, which in oneposition closes off the. pipe h, in another position opens up the' pipeh, and in another position closes the communicati'on-from the receptacle6 to the air-pum and opens a connection from the receptac'l for theentrance of the atmosphere.

dc is a pipe from the vacuum-tank, to the pipe h, connecting with thepipe h etweenv the three-way .valve-i and the air-pump, and in this lineof pipe is a two-way valve '1, which in one position opens upcommunication through the pipe 7c and in anotherposition closes off thesame. I r In the method employed, or, inother words, in the operation ofthe apparatus described, the air-pump g is being run, the

valve Z open, so that the pum 1s exhausting the vacuum-tank While 't 'sis proceeding the cans,-jars, or other packages the Govers of which areto be sealed byatrnospheric'j pressure are placed upon the platforms andshort distance-say one-fourth or, threethe receptacle is now closed andsecured,

valve 1', is closed in the line of pipelaand the a the platen d screweddown until withinf'a in the receptacle a partial vacuum. The valve Z isthen closed and the pump allowed to Work through the pipe h, exhaustingthe air only from the receptacle containing the cans, jars, &c,, until t1e desired vacuum is obtained. At this moment foot-pressure is appliedto the lever c, the rod 0 is elevated, raising the platform 0 andbringing the covers with force against the under side of the ro platend, and this footressure is mainmunication through said valve for theatmosphere to pass by the pi e it into the recep tacle and effectuallysea the covers. After the admission of air to the receptacle, which hasthe effect of balancing the pressure within the receptacle with that ofthe atmosphere, the platform 0 is to be lowered, so as to' free thecovers of the cans, jars, or other packa es of contact with the platend. The cover is now let down, so as to open up the receptacle for theremoval of the cans, jars,

, or other packages the covers of which have been sealed by atmosphericpressure. While the cans, jars, &c., are being removed from .35 thereceptacle and others placed therein the covers of which are to besealed the-yalve Z "is opened, so that the pump can work to exhaust theair from the vacuum-tank f. 1

The operation or method herein described 40 of sealing the covers ofcans, jars, &c is successively repeated. v

I claim as my invention 1 1. The combination with a receptacle adaptedto receive the cans, jars, &c., the

covers of which are to be sealed by atmospheric pressure, of avacuum-tank, an airpum a pipe extending from the air-pump to t ereceptacle, a branch pipe from the vacuum-tank to said pipe and valvesin said pipes by which a partialvacuum is first established in thereceptacle and then as complete a vacuum as desired and by whichthereafter the pressure in the machine and vacuum-tank may be equalizedfor the bene- 5 5 fit of the tank and air be then admitted to thereceptacle so that the same may be opened and the jars, cans, &'c., withtheir sealed covers removed and replaced by others to be sealed.

6o 2. The combination with a receptacle adapted to receive the cans,jars, &c., the covers of which are to be sealed by atmospheric pressure,of a vacuum-tank, an air- V pump, a pipe extending from the receptacle.ceptacle first and the pum covers of which are to be sealed by atmos-'vices connected to the receptacle for admitto the airump, athree-wa'yvalve in the line of sai ,pipe, a ipe from the vacuum tank totheaforesai "pipe connected therewith between the air-pump and -saidthreeway valve, and a two-way valve in the lineof said pipe.

3. A unitary apparatus forsealing the covers of cans, jars or otherpackages by atmospheric pressure, comprising a receptacle recelving saidcans, jars, &c., and adapted to be closed air-tight, devices connectedwith .75 said receptacle for pressing the covers of said cans, jars,&c.,. to'their seats and holding them temporarily under pressure, anadjacent vacuum-tank, an adjacent air-pump, a pipe from said rece tacleto said air-pumi'p by which the air may e exhausteddirectly om saidreceptacle, and a three-way valvethe line of'said pipe, a pipe from thevacuumtank to the aforesaid pipe joining therewith between the air-pumpand said three-way valve and a two-way valve in the line of said pipe,substantially as set fort/h.
